Did you know that WA State law requires that you install Carbon Monoxide Detectors prior to transferring property to the new buyer? Here is the rule…
The number of CO monitors required in any given home (new and resale), and the location of those monitors, is controlled by regulation adopted through the state building code. WAC 51.51.315 provides:
"… an approved carbon monoxide alarm shall be installed outside of each separate sleeping area in the immediate vicinity of the bedrooms in dwelling units and on each level of the dwelling and in accordance with the manufacturer's recommendations."
